Abstract: Based on a new aperiodic homogeneous Markov chain representation of M-ary PSK signals, a new matrix-based stochastic method for their spectral correlation evaluation is proposed. Explicit formulae for the spectral correlation function of these signals are derived and some calculated and graphically presented results of their spectral correlation characterization based on the proposed method are given, also.
Key words: Spectral correlations, PSK, Marcov chain.
